A Car (自動車) is a vehicle that is meant for land transportation. They are extremely common on Earth.
Bulma used to drive a car known as the 1980-1984 Renault 5 Turbo, but it was destroyed by Goku due to the latter mistaking it for a monster when they first met. Yamcha's favorite vehicle is his car, the Mighty Mouse. Monster Carrot's car looks like a rabbit. In Dragon Ball: Origins, it is revealed that Monster Carrot's car can launch explosive carrots (similar to missiles), jump, and fire Eye Lasers.
Master Roshi owns a Cadillac that he uses to go to the Training Island airport with Goku and Krillin in order to take an airplane for Papaya Island. Konkichi, the trouble-making fox that Goku rescued in a forest near Yahhoy, drives an old-fashioned Mini. In Yahhoy, Goku and Konkichi meet Fortuneteller Baba and Ghost Usher in their black car. Commander Red also has a car, although he has a chauffeur drive him around, and it also has a spring up seat, presumably as a means to make Commander Red feel taller.
The farmer who is the first human encountered Raditz upon his arrival on Earth, owns a pickup truck. King Kai owns a red 1957 Chevrolet Sedan Bel Air hardtop (a nod to the fact that Akira was born in the 50's). The guide that King Yemma provides to Goku owns a Messerschmitt KR that he uses to take Goku to the start of the Snake Way. Grand Kai owns a 1958 Cadillac Series 62 convertible blue in color. Krillin owns a Volkswagen Karmann Ghia, as seen when he introduced Maron to Gohan in the episode "The Heavens Tremble". In a filler episode of the Trunks Saga in Dragon Ball Z, "Goku's Ordeal", Goku and Piccolo are forced by Chi-Chi to take driving lessons; they drive another variant of simple cars, known as the hovercar, which are strikingly similar to Honda S800's. During the 10 days period prior to the Cell Games, after he got his driving license, Goku is seen driving a Messerschmitt KR while going to a picnic with his family.
Bulma is seen driving a red car in the second Dragon Ball Z opening and the second Dragon Ball Z ending, "We Gotta Power" and "We Were Angels". In Dragon Ball GT, it is revealed that Trunks owns a limousine.
